LEKFS, High Rigidity Ball Screw Slider, AC Servo Motor

The LEKFS slider is an electric actuator with a load mounting platform situated above a ballscrew drive.  LEKFS has the same external dimensions and mounting as LEFS, but LEKFS includes a redesigned guide with 4 rows of steel balls instead of 2.  This more rigid design decreases table movement, permits greater offset loads, and improves positioning repeatability.  Additional enhancements vs. the LEFS include standard auto switch mounting grooves and positioning pin holes, plus improved dustproof performance with magnetic seal band adhesion. This model is fitted with an AC servo motor with incremental or absolute encoder.  Optional drivers include pulse input and various communication protocols including Ethernet.
